(craze-2) 9 Claims. 1

' This invention relates to machines for placing jackets or wrappers on ice cream cones and the like. Such jackets are usually made of paper in the form of a truncated cone and envelope only the stem of the cone below the bowl, or below the nesting ring when such a ring is present on the cone. v 1

Primarily the invention has for an object to provide a machine, for the purpose stated, of a simple, inexpensive construction, a machine that is fully automatic in its operation, one that cupies but little space and is not costly to maintain.

Generically the machine comprises a magazine for the cones, a magazine for the jackets, a receiver for the jackets and cones, mechanism for removing the jackets, one at a time, from their magazine and placing them in the receiver, a mechanism for discharging the cones from their magazine into the jackets previously placed in the receiver, a device for pressing'the' cones into the jackets to secure the jackets to the cones, and finally a mechanism for discharging the lacketed cones from the machine and nesting the cones that have been discharged from the receiver as they are being delivered from the machine.

Other objects will in part be obvious and in part be pointed out hereinafter. i

To the attainment of the aforesaid objects and ends the invention still further resides in the novel details of construction, combination and arrangement of parts, all of which will be first fully described in the following detailed description, and then be particularly pointedout in the appended claims, reference being had to the accompanying drawings, in which: i

In the accompanying drawings in which like numbers of reference indicate like parts in all the figures, l represents the legs, 2 the lower longitudinal bars, 3 the intermediate longitudinal bars, 4 the upper longitudinal bars, the cross barsand 16! the frame braces of the main or base frame of the machine. c: Supported on the upper bars 4 of the machine is the stacking table top 5 having vertical 1onitudinal partitions 6 that divide the top into longitudinal troughs, one for each cone stack.

Mounted on transverse supports 1 is a speed control device 8 and a driving motor (electric preferably) 9, whose shaft 10 carries'two pulleys II and 12. These pulleys are made in two halves each, which halves are spring pressed together; as they are not a part of the present invention a further description and a detailed drawing thereof is not necessary.

The pulley ll drives, through a belt 15,:the pulley I4 on the driven shaft 64 of the reduction gearing (not shown) which is located in the housing l3, for driving the main shaft I 6 on which are fastened a setof cams H to l9 and 26 to 30 inclusive. i j v The cam I1 operates the swinging frame I20 of the jacket transferring mechanism; the cam l8 operates the cone presser I48; the cam ISoperates the lower cone releasing means; the cam 26 operates the jacketed cone retarder and nesting rod 6!; the cam 21 operates the plug carrier I30; the cam 28 operates the mold or jacketand-cone receiver '94; the'cam 29 operates the upper cone releasing means; and the cam 30.01 crates the vacuum valve I51, all of which will later be more fully explained.

A connecting rod 20 has a roller 23 to engage the cam I1. The rod 20 has its end that is remote from the cam pivoted to an arm I24 that is secured to the shaft I I9 of the jacket transfer mechanism. The roller 23 is constantly held in operative relation to the cam I1 by the spring I23 (seeFig. 5). The spring I23 continuously tends to swing .the frame I20 in a clockwise direction in Fig. 1, thereby continuously (through shaft H9 and arm I24) tends to move the rod 20 upwardly in Fig. 1 and consequently holds roller 23 against its cam.

A connecting rod 2! has a roller 24 to engage the cam 8. The end of the rod-which is 'remote from the roller 24 is connecting to-thea-rmi84 which is in turn secured to the rock shaft83. Links 81 are secured to a shaft 83-and are..connected to links 89, as at 88, which links 89 in turn carry the shaft v of the cone presser I41,

I48 (Fig. Rollers 9| -on the ends of the shaft 90 main horizontal guideways 92, each of which guideways has a downwardly directed. passageway 92 for the rollers 0| to pass down andbring the presser over the cone whichis located in the jacket in the jacket and-cone receiver 94 as will be more fullyiunderstood later. The shaft 03 has a second arm 85 to which a spring; 36 is connectediFig. l). The spring is anchored to the bar 34.

'A connecting rod 22 has a roller 25 to be engaged by the cam IS. The rod 22 isin turn connected'to the rocker 1ever50 on the operating shaft 42 of the cone releasing mechanism. A spring =5I is connected to the lever 50- andconnecting rod 22 as shown in Fig; 1.

*A connecting rod I62 is pivoted, at I63, tothe frame 58 and carries rollers I64 to cooperate with "the cam 26.

A connecting rod I04 has a pair of. rollers I05 to'engage'with the cam 21 (Fig. 3) and is pivoted on a rod I36 thatis mounted in ears I31 onthe plug carrier I30.

-An arm 69' is pivoted at to the-bar and carries a roller II that is held against the cam 28 by a stout spring 14. 'To the free end of the bar 69 is pivoted a connecting rod (58 whichin turn is pivoted to the arm 61- that isfastened to-the rock shaft55. The shaft'55 is mounted in the fixed blocks 93 that are-secured toand beneath the cross bar 91 that is mounted on the i side bars 34 of the sub-frame of the machine. A- crossbar 9B is secured beneath the bearing blocks 96 and to this bar 98 the upper end 99 of the chute I00 is fastened in any suitable way. The lower end I64 of the chute 400 is secured to a-erossbar165 that is mounted on the'frame sidebars 4.

A bell crank lever 39 is pivoted to-a stub shaft 38' that is mounted in a bearing 31.

The bell crank has a roller65 on one arm to be engaged by the cam 29. The other arm of the lever 39 is pivoted to a connecting rod 54 that is in turn pivoted to a rocker arm" 53 onthe operating shaft 41 of the cone releasing mechanism.

An' arm I54 on a rock shaft I53 has a roller I55 that is held in constant engagement with the cam 30 by means of a spring 65 that is congreeted to the arm I54 and to the bellcrank lever "The roller 66 is-held at the desired distance of-adjustmentwith respect to the cam 29 by reason of the fact that the shaft '41 at the end opposite that to which the arm 53 is attached has an arm 48 whichengages the adjustable stop 49.

The shaft 46 and-the shaft 43 of the-upper .frame,-comprisesthe uprights 32, the brackets SI, the longitudinal horizontal bars 33, the uprights 36 and side bars 34 and their downward extensions 35.

35 and are spaced therefrom by blocks Other uprights-4E! are mounted on the frame -bars-'34. To the-pairs of uprights 40, 40 are secured the; side plates 4! in and between which "llhe-uprig-htbars 40 of the cone magazine frame are secured to the downward extensions IB'E.

the shafts 43, 41 and 42, 52 are mounted.

Thehhafts 42, 43, 41, and 53 each carry plates Hill which are provided with curved recesses I60 in theirfree edges partly to embrace the cones C (Figs. 16 and 17). The shaft 42 also carries a safety cone-release plate I09 having recesses I69 that leave corners I59 to overlie the rims-of. the cones-caughtby the lower pair of plates I68 and push the cones free should they not drop by gravity when the lower plates move to release or drop-a cone into the jacket-and-conereceiver. The ia cket-and-cone receiver comprises two half moldlike members 94 which are slidably mounted on rods 95 that are carried by the hearing blocks 95. Therock shaft 55, at each end, has a rocker arm 56, one end of which arm-is linked to one member.94 by a long link I0! and the: other end of -whioh is linked to the other member-04 by an adjustable short link I02 so that as the: arm .56 is rocked the members 94 will be: separated (opened) or brought together (closedy-accordingly as the arm 56 is rocked in one, direction or. the other. i The frame 58; has, at its pivot end,-a.shaft 51 that is mounted in bearings on the mainframe bars 3. The frame 58, at its upper end, has a rod 59 towhich arms 60 are pivoted. These arms straddle the'chute. I00 and at their free ends they carry a rod BI which extends over and across the chute. At one end of the rod BI is a rollerfi3 which rides under and over a track 13, that is pivoted to abracket 12, and along a curved track 62. The bracket 12 is secured to the track 52 which in turn is-mounted on a sidebar 4 in any suitable-way, as by means of a bracket I16. A vacuum or suction pump" is mounted on axpair ofcrossbars-I60. The outlet 18 of the r pump; delivers to atmosphere while the intake 19 connects to a tank 80. The pump 1? is driven, via pulley BI and belt 82 from the pulley I2 on the shaft I0 of the motor 9. The tank is connected, via duct I58, to the vacuum control valve I51. 'The valve-151' has an adjustable yieldable connection I10 to the arm I53 (Fig. 1).

Thezsupporting frame of the jacket magazine is numbered I05 and is'mounted on the subframe'23, 32- and carries crossbars I08 on which theijacketholding tubes or magazines I01 are carried.

Guide rod supporting blocks H0, mounted on the frame-bars 23, carry the guide rods I09 on which'the jacket transfer plug carrier I30 is slidably mounted.

-A' bracket III is rigidly secured to a block IIO atone-side of themachine and to one of the side bars of theframe I06 (Figs. 1 and). This bracketcarr-ies a cam track H2.

"The swinging-frame of the jacket transfer mechanism carries a finger carrying shaft II3 on which a set of rigid fingers I21 is secured by set screws "I, there being one finger for each jacket tube I01. A bridge member composed of two or more arms II6 connected by a cross bar H1, is freely pivoted on the shaft H3. The bar '1 carries a set of spring fingers H8, one for each finger I21, and these fingers II8 are continuously pressed toward their associated fingers I'21 by a leaf spring I28 that is fastened to one of the fingers I21 (Fig. 12).

An arm I I4 is secured to the shaft I I3 and carries a roller II5 to cooperate with cam track II2, while-a rigid arm I26, on the bar II1, cooperates with a stop arm I secured to one of the frame bars.

One or both (one only being shown) of the frame bars I20 may be extended and provided with a notch I2I to serve as a stop or guide in adjusting the maximum elevation of the plug carrier I30.

An arm I44 is secured to the shaft II3 by a set screw I22 and carries a'stop lug I46 that may be engaged with the adjacent bar I20 when inthe position of Fig. 6 and when the shaft H3 is turned counter clockwise in Figs. 1 and 4 and after the roller I I5 leaves the end of the cam track II2, under the influence of the spring I45. The spring is anchored to frame I20 and to the arm I44 as shown.

The plug carrier I is hollow and has a nipple I3I connected to the flexible suction duct I59 that comes from valve I51. A set of nipples I43 on the carrier I30 carries a set of plugs I29. Each plug is of truncated cone or frusto-conical form and is designed to fit loosely within the jackets 10. At the side of the plug which faces the longitudinal slot I56 in the tube I01, the plug has a deep groove I32 to'receive a finger I21, while at the opposite side the plug has a shallow groove I33. The plug has a bore with a lateral duct or port I34 that terminates at the groove I33 (see Figs. 9, 10, 11, 14, and 15). Each plug I29 is provided with a pin point I35 (Fig. 9) or saw teeth I35 (Fig. 18) projecting into groove I33 so as to provide the plug with a rough place in the groove I33. When a jacket is sucked into groove I33 (Figs. 14 and 15) it will be caught by the pin I35 or teeth I 35 so that it cannot slip off the plug as the plug is being withdrawn from the magazine I01. Eachtube I01 has a slot through which a finger I39 projects into the tube to hold the stack of jackets w from dropping down through the tube I01. The finger I39 is secured (preferably adjustably) at I40 to a bracket I38 that is suitably fastened to the tube I01. Another bracket I4I, secured to the tube I 01, carries a spring finger I42 which presses the stack of jackets toward the side of the tube which carries the finger I39.

A rod I49 is secured to the pusher I48 and passes through a guide I50 and under shaft 83 and. serves to keep the pusher approximately horizontal at all times.

Brackets I12, secured to the bars 40, support the rods I13 which are arranged to hold the stacks. of nested cones, a guard plate I14 being provided and supported on a yoke I15, if desired.

An on and ofi switch I11 and mainline connection box I18 are provided and are of the usual construction.

Operation Assume that the tubes I01 contain a supply of jackets nested loosely with their larger ends down.

Assume that the cone holders I13 contain a supply of cones and assume that the parts are in the position shown in Figs. 1 to 4 inclusive. At this time a jacket and a cone will have been deposited in the receiver 94; a plug I29 will be located within the lowermost jacket of the stack ofjackets (as shown in Figs. 4 and 7) the transfer frame I20 will be at rest; the plug carrier will also be at rest. 1

As the parts pass from the position shown in Fig. 4 toward the position shown in Fig. 8, the lower plates I68 turn to their approximately horizontal position shown in Fig. 8; the pusher I41, I48 passes to the position shown in Fig. 8 and presses the cone C down into tight contact with the jacket w; the plug carrier I 30 moves down from its position in Fig. 4, the finger I21 enters the groove I32 to receive the jacket and strip it from the plug. While the plug was in the position of Fig. 4 the valve I51 was opened so. that suction was applied to deflect a portion of the innermost jacket into the groove I33 where it was held until the plug and jacket passed the finger I39 (Fig. 14). In passing from the position of Fig. 4 the roller 63 rides up the incline 13 and after the roller has passed over the top of that incline and dropped down on the track 62, the molds 94 are opened to discharge the jacketed cone which is then caught by the rod 6I and retarded in the chute while the rod continues to push a previously released cone onto the nesting table 5 and nest the cones.

As soon as a jacketed cone has been discharged from the mold, the mold is again closed; the presser is again withdrawn against stop '33; the jacket to Fig. 8 will have been deposited on the finger I21 and the transfer frame will move from the position of Fig. 8. As the frame I20 moves from the position of Fig. 8, the arm I26 will have left the stop I25 and spring I28 will have brought finger I I8 into pressure contact with the jacket on finger I21 to hold the jacket on the finger. By the time the parts reach the position of Fig. 5 the plug carrier will have reached its lowermost position and be starting up again; frame I20 and its carried parts will have reached the vertical position where the roller I, I5 is about to leave the track II2; the mold will be closing and will be fully closed before roller II5 leaves track 2. On leaving the position of Fig. 5, the roller II5 leaves the track H2 whereupon the spring I45 turns the shaft II3counter clockwise to invert the jacket; as soon as the arm I26 strikes the stop I03 the finger II8 will be released from the jacket and the jacket will be thrown into the mold small end down ('see dotted lines and full lines in Fig. 6).

In passing from the position of Fig. 5 toward that of Fig. 6, the upper plates I68 turn downwardly to release a cone from the cones above, whereupon the upper plates I68 move upwardly again and the released cone is caught by the lower plates I68 (see Fig. 6) and until the proper time for its release into the jacket within the mold.

On leaving the position of Fig. 6' the parts pass the position of Fig. '7 to the position of Fig. 8, during which time the lower plates I60 turn down to drop a cone into the jacket that has been deposited in the mold. This completes the cycle of operation.

In Fig. 19 is shown a modification of the plate I68. In this form a relatively thin plate I68 is used and the required thickness for engaging and holding the cones is built up by means of vacant-1's 7 sheet-metal members: N9 secured each cut-out portion; 16.81% of. the: plates. I68
